1. What is Spherical Cast Tungsten Carbide Powder?
Spherical Cast Tungsten Carbide Powder is a cast tungsten carbide material containing WC and W₂C phases that has been processed into predominantly spherical particles for improved powder handling and deposition characteristics.
2. What is Cast Tungsten Carbide Powder used for?
It is primarily used for thermal spray coatings, hardfacing, PTA welding, laser cladding, mining components, drilling equipment, oil and gas equipment, and other applications requiring extreme wear and abrasion resistance.
3. What is the difference between cast tungsten carbide and conventional WC powder?
Cast tungsten carbide typically contains a WC/W₂C phase structure and is valued for its exceptional hardness and wear resistance. Conventional cemented or sintered WC powders can have different compositions and processing characteristics.
4. What particle sizes are available?
Common grades include approximately 15–45 µm, 20–53 µm, and 45–90 µm, with custom particle-size distributions available for specific thermal spray and hardfacing processes.
5. Why is spherical morphology beneficial?
Spherical particles generally provide improved flowability, consistent powder feeding, higher packing density, and more uniform deposition, which can be beneficial for thermal spray and other powder-based coating processes.
6. Does REG Metals provide a Certificate of Analysis?
Yes. A Certificate of Analysis (COA) can be supplied documenting WC/W₂C phase composition, tungsten and carbon content, particle-size distribution, hardness, morphology, oxygen content, free carbon, and other applicable powder specifications.
